HEATING-STOVE.

.To @ZZ whom, t 771,607/ concern:

Be it known that I, LEWIS W. HEMP, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. Y

Myinvention relates to heatingstovesg and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

My object is to construct an improved heating-stove; and my invention consists of a suitable casing having a fuel-opening in the forward part of its top and having a chimney-opening in the rear part of its top and having draft-openings one on each side of the chimney-opening; draft-inlet dampers controlling said draft-openings; a fire-box mounted in said casing and held up from the bottom to form an air-space, said iire-boX being shortened at the rear to form a second airspace communicating with the rst air-space and with the chin1ney-opening, and said lirebox being shortened at the front to form a third airspace communicating with the first air-space and with the top of the fire-box; a wall extending upwardly from the rear edge of the tire-box `to the top of the casing in front of the chimney-opening, there being a damper-opening in said wall; a draft-directing damper in said damper-opening, and coldair flues leading from said draft-openings and comm unicating with the fire-box, so that when the damper is closed the air will pass th rough said draft openings, downwardly through said flues, upwardly through the ire-box, downwardly through said third airspace. backwardly under the irebox through said first airspace, upwardly through said second air-space, and out through said chimneyopening, and so that when the damper is open the air will pass downwardly through said flues, upwardly through the dre-box, and then through the damper-opening to the chimney-opening. n

Figure 1 is a vertical central section of a stove embodying the principles of my iuven tion. Fig. 2 is a top plan view, parts being broken away to illustrate their construction.

Fig. 3 is a vertical section through one of the draft-openings upon an enlarged scale.

Referring to the drawings in detail,- my improved heating-stove comprises a suitable casing 4, mounted upon legs 5 and having the fuel-opening 6 in the forward part of its top and having the chimney-opening 7 in the rear partof its rop and having the draftopenings S and 9, one on each side of the chimneyopening; draft-inlet dampers 10, controlling the draft-openings; the {ire-box 1l, mounted in the easing and held up from the bottom by means of the legs 12 to form the air-space 13, said fire-box being shortened at the rear to form the second air-space 14, communicating with the first air-space 13 and with the chimney-opening 7, and said fire-box being shortened at the front to form the third air-space 15, communicating with the tirst airspace and with the top ofthe fire-box; the'wall 1G, extending upwardly from the rear edge ot' the fire-box to the top of the casing in front ot' the chimney-opening 7, said wall having the chimney -opening 17; the draft-directing damper 18, mounted in said damper-opening, and the coldair lues 19 and 20, leading from the draft-openings 8 downwardly and communicating with the lower rear part of the fire-box 11 through the openings 21, formed in the fire-box. The cover 22 closes the fuelopening 6. The handle 23 serves asa means of operating the draft-directing damper 18. Vhen the draft-inlet dampers are opened and the draft-directing damper is closed, the air will pass thro ugh the openings 8 and 9,'through the cold-air dues 19 and 2O into the lower part of the fire-box, upwardly through the fireboX, downwardly through the air-space 15, backwardly under the fire-box through the ai rspace 13, upwardly through the air-space 14, and out through the chimney-opening 7. rIhus it will be seen that the hot air passes entirely around the fire as required to heat the front and bottom of the stove, as well as the rear part. If the draft-directing damper 1S is opened, as it should be when the fire is about to be started, the air will pass downwardly through the cold-air fines 19 and 2O and upwardly through the ire-box, through the dampereopening, and out through the chimney-opening.

IOC

Especial attention is called to the fact that the cold-air ues pass through the hot-air space leading to the chimney, thus heating the cold air before it passes into the fire-box.

I claim* A heating-stove comprisinga suitable oasing having a fuel-opening in the forward part of its top, and having a chimney-opening in the rear part of its top, and having draftopenings one on'eaoh` side of the chimneyopening; draft-inlet dampers controlling said draft-openings; a fire-box mounted in said easing and held up from the bottom to form part of the hot-air space, said fire-box being shortened at the rear to form a second part of the hot-air space communicating with the first hot-air space and with the chimney-opening, and said fire-box being shortened at the front to form a third part of the hot-air space communicating with the first hot-air space and with the top of the fire-box; a wall extending upwardly from the rear edge of the lire-box to the top of the casing in front of the ohimneyppening, there being damperopenings in said wall; adraft-directing damper in said damper-opening; and cold-air lues leading from said draft-openings through said second hot-air space and communicating with the fire-box; so that when the draftdirecting damper is closed the air will pass through said draft openings downwardly through said cold-air passages, upwardly through the tire-box, downwardly through said third hot-ail' space, baokwardly under the tire-box through said first hot-air space, upwardly through said second hot-air space, and out through said chimney-opening; and so that when the draft-directing damper is open the air will pass downwardly through said cold-air passages, upwardly through the fireboX, and then through the damper-opening to the ehimney-opening,substantially as speci-f ed.

In testimony whereof I aftix my signature in presence of two witnesses.

LEWIS W. HEMP.
